This communication presents a thermal anaysis of an active solar still for the optimization of collectors as well as
the basin area for a higher yield for a given water depth. Expressions for the temperatures, the water and glass covers
and the yield have been derived. In order to have numerical appreciation of the results, meteorological data for a summer
day of Delhi climate have been used. It has been observed that the optimization is a strong function of water depth.
